From BBC News:
The study estimated that the increased risk translated into one extra case of leukaemia and one extra brain tumour among 10,000 CT head scans of children aged under ten.
Dr Mark Pearce, an epidemiologist from Newcastle University who led the study, said: “We found significant increases in the risk of leukaemia and brain tumours, following CT in childhood and young adulthood.
“The immediate benefits of CT outweigh the risks in many settings.
“Doses have come down dramatically over time – but we need to do more to reduce them. This should be a priority for the clinical community and manufacturers.”
